Very unlikely that any international flights bound for the USA are taking off. Probably many are turning around or diverting if they are not more than halfway there.

I'm not following this very closely, but I've not seen any reports of diversions for domestic flights, so I think it'd be unlikely for international flights. The report is just for a ground stop, which is just a stop in departures; normally a ground stop would allow flights already in the air to travel to their normal destination.

That reasoning doesn't really make sense. A flight from outside the US that is inbound could divert to a non-US airport that isn't impacted by whatever is going on, depending on where they are and what their fuel status is. A domestic flight doesn't have a non-US airport to divert to.

(Sure, a flight near the Canadian or Mexican border could in theory divert to a Canadian or Mexican airport, but it's unlikely many people on those flights have their passports with them.)

Ah, my point was more that if the action being taken isn't "get planes on the ground _now_" and so the US airspace remains open for traffic already in the air, then it's unlikely they're trying to get international planes to either divert or return.

		This definitely feels like 'unable to manage normal volumes at normal speed' rather than 'unable to manage anything.' In which case freezing domestic (and the huge amount of load it contributes to ATC) but keeping international normal makes sense. Of course... the side effect is the "fun" that creates for incoming international flights with domestic connections...

There must be some procedures in place for this - I pretty regularly take domestic (Canadian) flights that pass over the US where I don't carry my passport.

		A situation kind of like this happened to a relative in England; their international flight was diverted (I think due to weather) to a domestic-only airport; due to lack of immigration & customs facilities, everyone had to remain on the plane until it could take off again (presumably after being refueled) to get to an international airport

A domestic US flight can still divert to Canada. There usually are special arrangements that allow people on a diverted flight to stay short-term while the situation is resolved, even if they don't have the required documents or visas.

		That is interesting and why i was wondering if they meant outbound flights but screwed up the language. I had assumed (probably wrongly) operators who should be risk averse would not want their US bound flights taking off under these conditions.
